Catecholamines, derived from the amino acid tyrosine, produced by the adrenal glands, which are found on top of the kidneys. are epinephrine (adrenaline), norepinephrine (noradrenaline) and dopamine. The hormone are released into the blood during times of physical or emotional stress.

          The Effects of hypertension on cardiovascular responses to epinephrine

Cardiac beta-receptor responsiveness is diminished by both aging and hypertension. In the study to evaluate of14 young and 18 older normotensive men and women and in 10 young and 17 older hypertensive men and women by echocardiography cardiac responses to intravenous infusion of epinephrine and to assess the relative contribution of intrinsic cardiac and counterregulatory components to the overall respons, found that Epinephrine-induced increases inheart rate were similar in the four groups. Increases in stroke volume, ejection fraction, and cardiac index were similar in the two hypertensive and two young normotensive groups. In contrast, they were attenuated in the older normotensive group, resulting in higher left ventricular responses in older hypertensive than in normotensive subjects. Heart rate and left ventricular responses to epinephrine in the presence of ganglionic blockade did not differ between the two young groups. Increases in plasma norepinephrine due to epinephrine infusion were larger in hypertensive than in normotensive subjects(10).
